Novel networking paradigms are enabling the introduction of innovative vertical use cases and new business relations in the B5G/6G mobile ecosystem. For instance, a use case may require the coordination of domains owned by different operators to provide service continuity and keep offering a vertical network service (NS) in similar conditions after a cross-border situation. This demonstration presents a procedure to perform a proactive service relocation in such a multi-administrative domain scenario considering an automotive use case. This demonstration proposes a cloud-native solution combining multiple enablers to manage the life-cycle of virtualised automotive NSs. During run-time, and upon registration, an AI/ML-based enabler decides proactively on the service relocation moment based on the collected vehicle’s positions and triggers an Integration Fabric enabler following ETSI ZSM guidelines to start a new instance of such automotive NS at the associated ETSI NFV management and orchestration stack present in the neighbouring administrative domain.

Virtual reality (VR) became, in the last few years, an important pillar for promoting cultural heritage (CH) through serious games or virtual guided tours. A lot of museums, institutes, and galleries tend to integrate new technologies like VR for promotion purposes. The major objective of this research is to analyze the Activator project through three immersive scenarios, developed in collaboration with the Center for Research and Technology Hellas (CERTH) and the “Noesis” Science Center and Technology Museum, and deal with three different regions of Ancient Greece. This study introduces the serious games VR platform Activator, whose purpose is to provide a realistic Query ID="Q2" Text="Article title: Kindly provide German article." VR experience coupled with a motion platform, to highlight a few significant moments of the ancient Greek civilization and let the user interact with key objects through a set of serious games in virtual environments. In particular, three immersive educational scenarios are implemented in the form of serious games, including the Siege of Rhodes, the Antikythera Wreck, and the First Settlement of Europe, which represents the volcanic eruption at Thera (Santorini). In addition to the implementation details and technologies utilized, the paper presents some preliminary evaluation results with real users, during its initial pilot phase that is currently carried out at the premises of the Noesis Science Center & Technology Museum, in Thessaloniki, Greece. The Activator platform, which has been developed in the context of a collaborative Greek national research project, will be available for public use after the end of the project.

5G architectures will utilize the virtualization of the network functions (VNF) and the use of Multi-access edge computing (MEC) to gain multiple benefits such as simpler service orchestration, while simultaneously covering diverse use cases even with strict performance requirements. 5G service orchestration mechanisms will need to allow more efficient and flexible network deployment and operations in a resourceefficient and delay-sensitive manner. A field that is expected to be greatly boosted by these advances, is Cellular Vehicle to Everything communications. 5G will enable cooperative, connected and automated mobility services, which are often are safety critical while also having stringent delay requirements. This paper, proposes a mechanism that predicts the future position of a vehicle moving in both urban and/or highway environments. Based on this knowledge, it decides on the optimal position of VNFs so that the allocation of network resources can be preemptively requested. The objective of this mechanism is to ensure the uninterrupted, continuous connections of the vehicles, resulting in minimal or no service interruption time while ensuring an optimal utilization of Edge Cloud and MEC resources.
